A Text Research On Table Tennis Players About Ball On To Determine The Reaction Time Of Placement

The table tennis is complex and changeable, five elements of table tennis (speed,power, position, rotation, the arc) significance of individual level in the table tenniscompetition are changing, especially highlighted the importance of hitting the ball. A newrule in the background, repetition consciousness and ability has become an important fieldof the race. And the table tennis athletes in the game not only to have the technical andtactical changeable, more need to be on the ball to make the rapid reaction ability. Tabletennis basic stroke links will judge as a first step, therefore, the main content of this paperis the table tennis players of judgment and reaction to the ball.In this study, the expert-novice paradigm, the experimental analysis of the subjects oncorrect rate ball judgment and reaction time. Select a player to serve themselves aftershooting sideways sights video as experimental stimuli, the Capital Institute of PhysicalEducation12majors and12non majors as subjects, the use of video by interceptingdifferent amount of information, video by subjects at the time of the specified keykeyboard recording in different projection speed, at the same time collection data, throughthe analysis of data.After the results of statistical analysis the following conclusions:1. Different projection speed not only for the group between reaction time and correct rateinfluence, also have an impact on the group. Table tennis match on the influencing factorsto judge the ball by cognitive speed, video cognitive faster, athletes on the field to judgethe ball faster. Therefore, cognitive speed experiment can be used as an indicator forselecting athletes.2. To determine the reaction time and correct rate of the influence of different amount ofinformation. Ball, ball, racket ball in three different amount of information judgmentdifficulty in increasing order. Fast professional group of players in the ball strength, speedof rotation is very good judgment and faster than other type of play players by making theball in an instant, the amateur group of judgment were staring at the ball, the lack ofjudgment. Therefore, the professional group of reaction time and correct rate than theamateur group.3. Professional group can search more visual information more effectively than the amateurgroup.
